Had the thing almost not bought because here are some reported they would have had to file off the screws ... I would not at all the tools to have had ... So when pointed screws which are rotated in rubber look up a notch out ... would be like then tighten it a try with much stronger? During installation, I had all the time to think and the reviews have to be as mad producer and seller when they read something. If the screws are not in rubber but only NEN bit press the rubber of the adapter because they were filed or sanded, then that thing is also located right ... not much fun when you have the knob times in the hand when shifting ... that the aluminum ring diaphragm is not screwed, means only that the screws are not tight enough ... actually ne clever idea, that yes each the screws completely pure turns on all sides ...
